Clear App Cache / Data:

NOTE: If one (or more) of your apps doesn't work correctly, you might be able to fix this behavior by clearing the app's cache. If that fails you can also proceed to clearing the app's data. WARNING! Clearing app data will remove all personal information stored within the app, including saved games, profiles, settings, credit card information etc.

  1. Press "Menu" while viewing the home screen
  2. Tap "System Settings" > "General"
  3. Under "Device", tap "Apps"
  4. Access the "All" screen and select the application
  5. Tap "Clear cache". If needed, tap "Clear data"
  6. Press "OK" to confirm

Wipe the Phone's Cache Partition:

NOTE: If your phone is not working properly, it freezes, crashes etc. you can try fixing these issues by clearing the phone's cache partition. Unlike a master reset, a partition cache wipe will not result in the deletion of personal data stored on the internal memory.

  1. Tap "Apps" from the home screen
  2. Go to "Settings"
  3. From the "General" tab, tap "Storage"
  4. Wait for the phone to finish calculating the data, then tap "Cached data"
  5. Tap "OK" and wait for the cache to be cleared. This process may take a few seconds or more
  6. Once the process completes, you should no longer see any cached data listed on the screen

NOTE: If wiping the cache partition didn't help in fixing the issue, you may want to try factory resetting your device. You can visit this thread for a full guide on how to master reset the LG Ultimate 2.

Entering Safe Mode to Remove Unwanted Apps:

NOTE: If one of your apps prevents you from uninstalling it, you can easily remove it by first rebooting your phone in Safe mode. In this mode all third party apps are disabled, and whatever process was preventing you from removing the app should no longer run. To enter Safe mode:

  1. Press and hold the "Power" button (while the phone is turned on)
  2. Tap and hold the "Power off" option
  3. Tap "OK"
  4. Wait for your device to reboot in safe mode. A "Safe Mode" label in the lower-left corner of the home screen will confirm if successful
  5. From the home screen, press "Menu"
  6. Tap "System settings" > "General"
  7. Under "Device", tap "Apps"
  8. Swipe to "All" and select the app you wish to remove
  9. Tap "Uninstall" > "OK"
  10. The app should be successfully removed. To exit safe mode press "Power", tap "Power off and restart" > "OK"
